The X Factor reveals winner’s single will be a DUET as finalists perform with famous faces Wyclef Jean, Paloma Faith and Tokio Myers

X FACTOR have put a spin on their traditional winner’s single release this year – and instead have announced that whoever takes home the top prize tomorrow will release a duet.

The series winner will be releasing the single with the famous faces they performed with on Saturday night’s show.

Viewers were able to hear their songs up for offer on tonight’s show, where the guest stars were revealed to a stadium audience at London’s Excel Arena.

Kevin Davy White performed with Tokio Myers and reprised Fast Love - which he originally sang during George Michael week - with the Britain's Got Talent singer.

Unfortunately, despite the song being received well and his performance praised by BGT winner Tokio, it wasn't enough to save Kevin, and he was sent home before the final performance.

Grace Davies performed original song Roots with Paloma Faith.

The song was what Grace performed in her first ever audition - and left the judges in tears before putting her through.

Rak-Su teamed up with Naughty Boy and Perfect Gentleman star Wyclef Jean for their own song, Dimelo.

Creating the song during their time in the house, Wyclef insisted he needed to "jump on a plane" to join them for the performance on Saturday's show.

The song will be released after the announcement of the winner of the series is crowned tomorrow evening.

All proceeds from the song will be donated to children’s charities, Together for Short Lives and Shooting Star Chase.

Simco Limited will donate 100% of its profits from the sale of each download and in respect of all audio streaming of the single.

The Chancellor has also agreed to donate the VAT, in each case to be shared equally by the two charities.

Dermot O’Leary announced the charity single plans on an intense show that saw the three contestants cut down to two.

Simon Cowell declared that he wanted to raise £1million for the two charities and their life-saving work.

As a starting point, the media mogul put his money where is mouth is - and donated £250,000 to start off the fundraising himself.

Following the finale this weekend, The X Factor hopefuls will be heading out on tour from February next year - with a Sun Online voted wildcard joining them.

Rak-Su, Grace Davies, Kevin Davy White, Lloyd Macey, The Cutkelvins and Matt Linnen will be serenading the UK in stadiums - but who do you want to see join them?
